Given your definition of intelligent design, that is a neat and tidy definition of panspermia, AG. Easily understandable and reference to your prior discussions. You have simply named the type of intelligence involved.
If panspermia is cosmic seeding, who or what are the seeders?
It could be God, "Gaia", intelligent beings putting "seeds" on probes capable of surviving space travel (or as we did when we accidentally put bacteria on the moon), some emergent (or fractal) intelligence that itself achieves velocity of matter (which carries the capability of emergence) in order to escape the gravity of its origin and protect itself in space travel.
The concept is not far afield of exogenesis, the difference is in the properties - "engineering" for emergence on the receiving end.
I understand that scientists today are considering something like this to continue life elsewhere in the cosmos as our own sun cannot survive forever.
